Space as first caracter in path will be deleted during rename

[sat24]

Hi,
I have updated to 3.19 64bit, coming from 2.99a. One of my mp3 folder path is "d:\mp3\verschiebene a-z\ top xxx\top100\2023.02.27". The " top xxx" has a space in front to get it on top in explorer. After renaming all files in 2023.02.27, this folder is empty, the result was created in a new path ...\top100\2023-02 without space.
I thought it is deleted and have tried it again, but with the errormessage I found the bug:

It is the same in 32bit.

This seems not to be a bug, just to prevent an invalid folder name on Windows (since Mp3tag v3.11f):

Error renaming files

Good morning, after the last update i have this problem: All my files are under a directory with this schema : " - 1992\name artist\album" before the update when i rename the files I don't have any problem. Now when i rename a file is created a new directory without the space before the "-" and all the subdirectory.. Is only my system affected or other persona have a same problerm? I using with same problems windows 7 and windows 10. Grazie From Italy
